Linus Torvalds 43644679a1 x86: fix power-of-2 round_up/round_down macros ... These macros had two bugs: - the type of the mask was not correctly expanded to the full size of the argument being expanded, resulting in possible loss of high bits when mixing types. - the alignment argument was evaluated twice, despite the macro looking like a fancy function (but it really does need to be a macro, since it works on arbitrary integer types) Noticed by Peter Anvin, and with a fix that is a modification of his suggestion (bug noticed by Yinghai Lu).
